At his new school, Percy Jackson discovers that two of the cheerleaders are empousai, a dangerous kind of female demon that have one metal leg and one goat leg. One he manages to kill, but the other one lets the music room go up in flames, so Percy has to flee.
At camp Half-Blood, his friend, Annabeth, has been chosen to lead a quest through the legendary labyrinth, built by the inventor Daedalus. Enemy troops are trying to find Ariadne's string, the only way to navigate the labyrinth. All Percy and his friends have to do is to find  the string and come back to camp Half-Blood. But this quest turns out a lot more dangerous than Annabeth, Percy, Grover and Tyson think.
A dangerous adventure packed with pure action, nothing more...
